totally appreciate that, i would like to use it BUT how then do i incorporate it back to this toolkit in order to use all the cool controls and exisitng programming i've done- or am i misunderstanding--- is the facebookgraphtooolkit an extension of
the FDK? Or is there sample code to illustrate interoperability? Thanks so much!

The Facebook Graph Toolkit isn't an extension on Facebook Toolkit. I created FGT because, in my opinion, the Facebook Toolkit is overly complicated and prone to breakage when facebook makes changes to their api. FGT uses the new dynamic feature in C# 4.0
as the return type for all facebook queries and as a result will handle changes to Facebook's api without modifications to the framework. FGT was designed to operate nearly identically to Facebook's official PHP and Javascript SDKs. For example, you can call
FB.api("/me") in the javascript SDK and you can app.Api('/me") in FGT in C# and the two libraries will return exactly the same data in the exact format. If you are maintaining an existing project, it may be too much work to switch over. However,
my experience is that in the long run you will have much less trouble with the new FGT.

On another note, we are still adding features to the FGT. What types of controls are you using? What controls would you like to see in our toolkit if you were to start using it?
